Patented Dec. 4, 1906.

Application filed February 5, 1906. Serial No. 299,438.

To all whom it may concern:

Be it known that I, SIGMUND SZENTJAN- ossY, a citizen of Austria-Hun 'ary, residin at New York, in the county of ew York an State of New York, have invented certain new and useful Improvements in Bridge and Door Operating Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to bridges for use in connection with doors or gates on elevated railways and subway railways for closing the space between the door or gate of a car and the platform at the side of a train or at the side of a railway-track; and the object of the invention is to provide a bridge of this class which is operated in connection with a sliding door or gate, the bridge being pivoted and ada ted to be raised and lowered vertically, whi e the door or gate is slidably mounted and adapted to be opened and closed in the manner of other doors or gates of this class, a further object being to provide a bridge and door or gate operated in the manner specified for use wherever such devices are app icable; and with these and other objects in view the invention consists of an apparatus of the class specified constructed and operated as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional end view of a part of one end of a car provided with my improvement and showing also a part of the platform of a station adjacent thereto, and Fig. 2 a vertical section of a part of the car on the line 2 2 ofFig.1.

In the drawin s forming part of this specification I have s own at a a part of the bottom of one end portion of a car and at a a part of one of the side Walls of the car, and at I have shown a part of a station-platform.

The car is provided in the side thereof adj acent to the end with a slidin door or gate 0, and pivoted or hinged at the bottom thereof, as shown at 0 is a bridge d, one side or end portion of which is provided with an arm (P, which projects inwardly and downwardly and with which is connected a link member 6, which extends upwardly and inwardly and is pivotally connected at 6 with a lever f,

pivoted at f, and with which is connected a 9 said operating-lever being pivoted at 7L2.

have also shown at c a sliding door or gate which is adapted to be operated or opened and closed at the same time as the bridge (1, and for this purpose I provide an operatingarm 7', which is pivoted at the same point as the link member e, as shown at f, and to the arm 61 of the bridge cl, and this arm extends upwardly and at an inclination to the door or gate frame and is pivoted at to a crank j, which is pivoted at 7' to any suitable support 7'", arranged adjacent to the side of the car and on the inner side thereof, and the crank 7' is pivoted at y' to a lever-bar 7c, one end of which is rovided with a pin k movable in a slot 7?, formed in avertically-arranged plate 764, secured to the inner side of the door or gate, or said slot may be formed in said door or gate, and the upper end of the lever-bar 7c is plvoted to the support y' at F. My invention is not limited to any particular construction of the bridge and door or gate, and it will be apparent that my improvement may be used in connection with any kind or class of cars which are operated in connection with elevated platforms at stations and similar places, so as to close the space between the car or cars and the platform, and thus prevent serious and sometimes fatal accidents occasioned by people falling or stepping into said space.

The invention herein described and claimed is an improvement on that described and claimed in United States Letters .Patent No. 791,659, granted to me June 6, 1905, and is distinguished from said invention by the fact that the bridge is a bin ed bridge instead of a sliding bridge and 1n the method of and apparatus for operating said bridge and the gate or door.

It will be observed that when the door or gate is closed the bridge is held in a raised position adjacent thereto, and the movement of the lever 72, in one direction will open the door or gate and lower the bridge, and the movement of said lever in the opposite direction will close the door or gate and raise the bridge.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with the door or gate frame of a car, of a sliding door or gate mounted therein, and a platform-bridgehinged at the bottom of the door or gate and on the outer side thereof, said bridge being provided with a downwardly and inwardly directed arm, a link member pivoted to said arm and extending upwardly and inwardly, a lever pivoted to said link member, a supplemental link member pivoted to said lever, an

operating-lever pivoted to the supplemental link member, an operating-arm also pivoted to the arm of the bridge and extendin upwardly within the door or gate, a crank' ever to which said operating-arm is pivoted, and

1 a lever-bar pivotally supported above the crank-lever and pivotally and slidably connected with the door or ate.

In testimony that I c aim the foregoing as my invention I have signed my name, 1n presence of the subscribing witnesses, this 3d day of February, 1906.
